But if you want to avoid the cors error and scrap or fetch or get the HTML of the website. Just like view-source:--websiteURL-- . You can use the API Provided by WhollyAPI - https://sh20raj.gitbook.io/whollyapi/

i.e. :- https://whollyapi.vercel.app/api/html?url=

For Example :- https://whollyapi.vercel.app/api/html?url=https://example.com


Now, Let's Fetch

let i = await fetch('https://whollyapi.vercel.app/api/html?url=https://example.com')

// Directly Fetching in Text Format
 i = await (await fetch('https://whollyapi.vercel.app/api/html?url=https://example.com')).text()
